Step-by-step explanation:
To solve this system of equation, let's multiply the second equation by two so both equations have a :
Next, let's add the two equations together to remove the and solve for :
Now that we have the value of , we can plug it into either of the equations to solve for :
or
Therefore, the solution to this system of equations is .

The solution of the given system of equation is x = 2 and y = 1
Step-by-step explanation:
Given,
x+2y = 4 eq 1
2x -y = 3 eq 2
To find the value of x and y
Putting y = 2x-3 from eq 2 in eq 1 we get,
x+2(2x-3) = 4
or, x+4x-6 = 4
or, 5x = 10
or, x = 2
Again,
From eq 2 we get,
y = 2×2-3 = 1
Hence,
x = 2 and y = 1
Checking:
Putting the values of x=2 and y=1 in eq 1 and eq 2 we get,
2 + 2×1 = 4 and
2×2-1 = 3
